Here's a local club that might let you tag along: http://www.spinmafia.com/

Your best bet is to contact RABA.

The 804 or the whole state for that matter is great for cycling. You have just about every type of terrain except for desert. And all of it is within 1-3 hours driving distance if you live in the middle of the state. Lots of rural roads, and the towns are not that far apart. History is everywhere as well as beautiful scenery.

If it was mid May, here are 2 organized rides you could go on. One is on the flat coast. The other is in the mountains. I am doing SOTR this year.
